Title: Communication method and system for moving object
Inventor: ITO SADAO
IPC: H04W60/00
Filed: 1988-04-01
Abstract: PURPOSE:To realize the communication with a moving object with no hit by switching a channel to another one for communication with another radio base station which satisfies the fixed communication quality in case a channel having the communication quality less than a fixed level while the same communication contents are transferred via plural channels. CONSTITUTION:When a mobile radio equipment moves to a radio base station 30-n from another radio base station 30-1, the speech quality is deteriorated between the ratio equipment and the station 30-1. Then an S/N monitor part 56 of a 1st type switchboard 20-I detects said deterioration and compares the information on the C/N values, etc., received from the stations 30-n, etc., with each other and decides the approach to the periphery of the talking zone of the station 30-n to perform the switch of channels. A switching transmission/ reception period when the channels CH1 and CH2-CHn are transmitted/received in parallel with each other lasts until the confirmation of the channel CHn and until the switchboard 20-I confirmed that the quality of the CHn is higher than a fixed level L2. Hereafter the channel CH1 is opened for continuation of the communication with no hit.

IPC: H04N13/00
Filed: 1980-06-14
Abstract: PURPOSE:To enable to make equal an image pickup interval for a left and right image to the interval of human eyes, by executing an image pickup with one camera through assuming an optical signal of a two-transmission system as one transmission system by the use of an optical shutter and an optical wave director. CONSTITUTION:An optical shutter 5 consists of a pair of window holes 7L, 7R provided with an equal interval (d) as the interval of human eyes, shutter plates 8L, 8R shutting and opening an optical path for the window holes plus motors 9L, 9R. Left and right lights PL, PR from the shutter 5 are applied to an image pickup device 15 after being unified into one optical path. The device 15 gives a left and right sequential signal to a mixer 18 corresponding to an alternate optical image from the shutter 5. The mixer 18 mixes a synchronizing signal from a synchronizing signal generator 17 and outputs a composite video signal to a terminal 19. Thus, even a stereoscopic image having an interval corresponding to the interval of human eyes is formed.

Title: Self-exciting switching regulator
Inventor: YONEYAMA NAOAKI
IPC: H02M3/335
Filed: 1981-05-29
Abstract: PURPOSE:To realize a small and lightweight transformer and at the same time  to prevent the breakdown of a circuit element, by setting a larger number of  turns for the input winding of a transformer used to a switching regulator than  that of the output winding and at the same time providing a protecting circuit. CONSTITUTION:The number of turns of an input winding P is set larger than that of a secondary winding S for a converter transformer 5. AS a result, a small and lightweight structure is realized for the transformer 5. However, the leak inductance increases. In case the leak inductance causes an overcurrent while a control transistor TR6 is on, this overcurrent passes through a detecting resistance 31. Then the current flowing across the resistance 31 increases more than the set value decided by a constant voltage diode 33. Thus a protecting TR32 is turned on, and a charge/discharge control TR37 is turned off. Then a time constant capacitor 36 is charged forward to turn off a TR6. Thus the TR6 is protected. At the same time, the TR32 is turned on when the output voltage increases and exceeds the Zener voltage of a constant voltage diode 38. And the TR6 is turned off.

Title: Method and device for observing and inspecting wiring current of semiconductor device
Inventor: FUTAGAWA KIYOSHI
IPC: G01R31/302
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To provide a method for observing and inspecting wiring current of a semiconductor device with no occurrence of electron/positive hole pair under beam irradiation, nor destructive element such as ion beam. SOLUTION: An integrated circuit 12 which is placed on a sample stage 21 as a sample is irradiated with infrared ray laser beam 11 from an infrared ray laser light source 23 through a microscope part main body 24 and an objective lens 25. With a power source terminal of the integrated circuit 12 connected to a constant voltage source 15, a resistance change at a wiring part under beam causes change in current at a ground terminal and a current change detecting part 17 detects it. A system control/signal processing part 27 processes the signal to display a current image, defective image, or current waveform on an image/waveform display part 28. Since infrared ray is used instead of conventional visible light, no electron/positive hole pair occurs with no destructive element such as ion beam.

Abstract: PROBLEM TO BE SOLVED: To enable detecting the state of the output end of an inverter circuit using small amounts of inexpensive parts in a circuit controlling the voltage supply to the inverter circuit while detecting the state of the output end of the inverter circuit. SOLUTION: A voltage which is generated in a current detecting resistance R provided on the primary side of an inverter circuit 2 where voltage is far lower than that on the secondary side of the inverter circuit 2, is compared with a reference voltage at a comparator circuit 7 to detect the state of the output end of the inverter circuit 2. Therefore, the need to use high withstand voltage parts in the current detecting resistance R and the comparator circuit 7 for observing the state of the output end of the inverter circuit 2 is eliminated and hence parts costs are reduced and the reliability of the parts is maintained.  Also, because the state of the output end of the inverter circuit 2 can be observed by such simple circuit configuration as consisting only of the current detecting resistance R and the comparator circuit 7, the number of part items is reduced, which also results in reduced parts costs.
